Pretreatment: the key to unlocking low‐cost cellulosic ethanol
New transportation fuels are badly needed to reduce our heavy dependence on imported oil and to reduce the release of greenhouse gases that cause global climate change; cellulosic biomass is the onlyExpand

Physical and chemical characterizations of corn stover and poplar solids resulting from leading pretreatment technologies.
In order to investigate changes in substrate chemical and physical features after pretreatment, several characterizations were performed on untreated (UT) corn stover and poplar and their solidsExpand

Lignin Valorization: Improving Lignin Processing in the Biorefinery
Background Lignin, nature’s dominant aromatic polymer, is found in most terrestrial plants in the approximate range of 15 to 40% dry weight and provides structural integrity. Traditionally, mostExpand

Lignin content in natural Populus variants affects sugar release
The primary obstacle to producing renewable fuels from lignocellulosic biomass is a plant's recalcitrance to releasing sugars bound in the cell wall. From a sample set of wood cores representingExpand

Combined sugar yields for dilute sulfuric acid pretreatment of corn stover followed by enzymatic hydrolysis of the remaining solids.
A number of previous studies determined dilute acid pretreatment conditions that maximize xylose yields from pretreatment or glucose yields from subsequent digestion of the pretreated cellulose, butExpand

Xylooligomers are strong inhibitors of cellulose hydrolysis by enzymes.
Typically, the enzymatic hydrolysis rate of lignocellulosic biomass is fast initially but then slows down more rapidly than can be explained by just consumption of substrate. Although several factorsExpand
